Open the original (DOI 10.1145/2858036.2858233)- What it measures
- The authors grouped each typist's finger-to-key mapping with hierarchical clustering. The techniques range from one-finger input to multi-finger input.
- What it does not show
- The clusters describe the 30 study participants only. The number of clusters depends on the clustering method.
